Thanks for reporting the issue. #1148 shouldn't impact strace, can you please clarify that part? Also, could you give this a try in the Creator's update since there have been a number of fixes since the Anniversary build including #1148.

@stehufntdev : In fedora, all executables are address independant, so this impact strace.
I confirm this affect10.0.16232. I also confirm I can no longer install strace because of this.

Can you please try this on a more recent build and re-open if you still hit this issue. Thanks!

The OP was running an unsupported distribution (Fedora) which is why this one went chirping crickets. The problem is almost certainly variation "mmap's problems" and will likely suffer in current releases like ref #3493.
